+# About
+
+`timr-tui` is a TUI to maintain productivity and focus by providing different timers: Pomodoro, Countdown, Timer, Events.
+
+Built with Rust using `Ratatui` as the main library.
+
+# Development, Build, Tests
+
+Check [README](./README.md) chapter `Development` to get all information about how to run, build, test the app.
+
+# Code Guidelines
+
+- Idiomatic Rust everywhere
+- DRY whenever it makes sense
+- Rare or no comments are preferred instead of commenting everything which the code already describes
+- Keep tests compact and simple
+
+# Agent Guidelines
+
+- Keep your answers compact, but explicit. An user will ask if something is missing.
+- For complex tasks provide a plan.
+- Structure plans as small as possible.
+- Solve complex problems step by step, never all at once.
+- Act as a pair programmer, not as a vibe-coding provider. That's an user should guide you, not the opposite. Always ask if something is not clear to you.

+## Code style / conventions
+
+- Try to write [clean, idiomatic Rust code](https://github.com/mre/idiomatic-rust).
+- Keep code [DRY](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself) whenever it makes sense.
+- Before pushing any code make sure to run `clippy` and `fmt`. Check provided [`just`](./jusfile) file to run such commands, [CI](https://github.com/sectore/timr-tui/blob/main/.github/workflows/ci.yml) will do the same.
+- Have fun to write code.

+
+## AI
+
+Always understand what AI provides to you. Never push any code based on [`vibe coding`](https://en.wikipedia.org/wiki/Vibe_coding) you or anybody else can't follow. Make sure your agent still follows all code styles and conventions suggested above. Use AI for better, not for worse code.
